3. DFN Association: Targets • Higher Education and Research (universities, research institutes) • Institutions with close relationship to the research and education com-munity • Research departments of industry • Government agencies

4. DFN Association: Objectives • Provision of national and inter- national connectivity • Bundling the requirements of the community to achieve better com- mercial conditions on the market • Testbeds for next generation communication technologies • Promotion of new applications • Organisation of international collaboration

5. DFN Association: Finance • Non-profit organisation • Subsidies from federal government only for development projects and for start-up phase • Operational cost (capacity, equip- ment, personnel, services ...) must be fully covered by income:  charges for services

6. G-WiN Technology (1) • WDM/SDH platform for IP traffic • Point-to-Point service (flexible capacity provision) • ATM service (flexible capacity and QoS provision)

7. G-WiN Technology (2) • Within backbone flexible provision of capacity according to changing user demands, lead time 1 hour • up to 60 * E3 point-to-point connections switchable at any time • provision of larger capacities within six weeks

8. G-WiN Technology (3) G-WiN Backbone Customer Router Backbone Router (28)

9. G-WiN Services (1) • Available services - Access to backbone from E1 up to OC-48 - Point-to-Point at E1, E3 - ATM at E1, E3 • CoS / QoS: under way - urgently needed for many appli- cations - required: service definition and organisational concepts

10. G-WiN Services (2) • DFNInternet: nat‘l connectivity and global transit • DFNConnect: point-to-point service • DFN-ATM: ATM-service at additional charge • Add. Services: at additional charge (QoS, ...)

11. Procurement • European Tendering for lotawarded to - backbone Deutsche Telekom - access lines various companies - routers Cisco - transatlantic Deutsche Telekom connectivity

12. G-WiN Characteristics • Suitable platform for future traffic growth and for high performance applications • Implementation of latest available field proven technology, now SDH/WDM, later WDM end-to-end • Reasonable cost/bandwidth relation • Availability of „protected“ connec- tions for specific applications and experiments (point-to-point service)

13. International Connectivity • Capacity to US now 2 * OC-12 (into Telehouse, NYC) • Capacity to TEN-155 upgraded to OC-12 • Access to Abilene in NYC at 100 Mbps, together with DANTE • Access to Canarie in NYC at 15 Mbps, together with DANTE • Access to STARTAP via Abilene‘s Internat‘l Transit Network Service
